CAR-AXLE BOX.

SPECIFICATION forming part of Letters Patent No. 332,112, dated December8, 1885.

Application filed October 12, 1885. Serial No. 179,583. (No model.)

To all whom it may concern:

Be it known that I, JOHN SAGMEISTER, a citizen of the United States, anda resident of Omaha, in the county of Douglas and State of Nebraska,have invented certain new and useful Improvements in Oar-Axle Boxes; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, which form a part of this specification,and in which Figure 1 is a longitudinal vertical sectional view of myimproved car-axle box. Fig. 2 is a cross-section on line x x, Fig. l.Fig. 3 is a horizontal section of the same. Figs. 4 and 5 areperspective views of the dust-plates, showing them separated and fromopposite sides, and Fig. 6 is a perspective view of the box.

Similar letters of reference indicate corresponding parts in all thefigures,

My invention has relation to car-axle boxes having dust-plates at theapertures in the inner end of the box for the purpose of closing theaperture in that end surrounding the axle; and it consists in theimproved construction and combination of parts of the same, ashereinafter more fully described and claimed.

In the accompanying drawings, the letter A indicates the axle-box, whichis of the usual form, but entirely closed with the exception of anaperture, B, in its upper side, an aperture, C, in its lower side, anaperture, D, in its outer end, and the aperture E in its inner end,through which aperture the axle F passes, the said aperture beingslightly oblong, so as to allow the axle to move vertically in the same.The aperture B in the upper side is provided with a sliding cover, G,while the apertures C and D are provided with covers H and l, lined withwood or similar material upon their inner sides and screwed upon thebox, forming perfectly tight covers. The inside of the inner end pieceof the box is provided with two vertical iianges having their edges bentinward, the flanges being lettered J J and the inwardly-bent edges K.The dust plates or shields L and M slide in the ways formed by theflanges, the side edges of the upper plate, L, fitting tightly under theinwardly-bent edges of the ilanges, but having lateral play under thesame. The upper plate, L, has a slot, N, opening from its lower edge andextending to the middle of the plate, where its end is rounded, as shownat O, so as to fit upon the upper side of thejournal of the axle, andthe outer side of the plate has two parallel grooves, l? P, near itsside edges. The lower plate, M, has a slot, Q, extending toward itsmiddle from its upper edge and ending in a rounded portion, R, whichfit-s against the lower halt` of the journal of the axle, and the legs SS or portions of the plate at the sides of the slot iit and slide in thegrooves of the upper plate, while its enlarged middle portion, T, belowthe rounded portion of the slot, its into the lower end of the slot ofthe upper plate. All the sliding portions of the two plates t perfectlyoil and dust tight upon eachother. The outer faces of these plates bearagainst the inside of .the inner end piece of thejournalbox, and theaperture of the same is formed with a groove or shoulder, U, into whichis placed a ring, V, of rubber or similar yielding material, which isretained by means of aring, U', secured in the groove and clamping theelastic ring between it and the bottom of the groove, the said yieldingring forming atight packing around the aperture in the inner end piece.through which the axle passes, and around which aperture the groove orshoulder is upon the inner end of the said side piece. The inner facesof the plates are provided, at the upper end of the upper plate and atthe lower end of the lower plate, with two crossbars, W W`, having theirends bent outward, so as to project outside of the flanges, and theseends are provided with hooks X, respectively:

pointing upward and down, upon which hooks the eyed endsY of two spiralsprings, ZZ, are hooked. It will be seen that these springs will serveto draw the two plates toward each other, causing the rounded ends ofthe slots to bear tightly against the journal of the axle, and thuspreventing any oil from escaping or any dust from entering, and theplates will have sufcient vertical and lateral play under the edges ofthe flanges upon the inner side of the box to allow the axle to give toany unevenness in its revolutions. The entire box is filled with oil,and the tight closures of the apertures in the box will prevent the oilfrom es- IOO caping or dust from entering, so that the journal may runinthe box for a considerable time without any necessity for filling thebox or for paying any attention to it. The sliding plates may beinserted from above and below, straddling the axle, whereupon thesprings may be first secured to the hooks of the lower plate, andthereupon to the hooks of the upper plate, whereupon the covers maybesecured by their screws, the box filled with oil, and at last the upperaperture covered by its sliding cover. The aperture in the outer end ofthe box is mainly for the purpose of inserting` the bearing-block, whichof course may be of any desired construction.

Having thus described my invention, I claim and desire to 'secure byLetters Patent of the United States- 1. The combination of the boxhaving an oblong aperture in its inner end surrounded upon the inside byagroove having a packingring laid into it, a journal projecting throughthe aperture in the box, and a set of dustplates tting tightly aroundthe axle and against the inside of the inner end of the box, as and forthe purpose shown and set forth.

2. A journal-box having an aperture in its upper and lower side and anaperture for the axle in its inner end, and having an aperture in itsouter endfor the insertion of the bearing-block, the apertures at theupper and lower side and at the outer end having tightly-fitting covers,as and for the purpose shown and set forth.

3. rIhe combination of a journal-box having apertures at its upper andlower sides, an axle passing through an aperture in the inner end of thebox, and dust-plates bearing with the ends of their slots against thejournal and having springs for drawing them together, the said platesbeing inserted through the apertures in the box, as and for the purposeshown and set forth.

In testimony that I claim the foregoing as my own I have hereunto afxedmy signature in presence of two witnesses. y
